Final answer:
Retractable lanyards are indeed suitable for fall protection and are designed to allow workers to move freely while maintaining safety. They lock automatically in the event of a fall, so they do not require constant adjustment and can be compact in design.
Step-by-step explanation:
The question about retractable lanyards pertains to their use in fall protection systems. Retractable lanyards, otherwise known as self-retracting lifelines (SRLs), are a type of fall protection equipment designed to arrest a fall. The correct option is that they allow workers to move freely while maintaining fall protection.
These devices have a mechanism that locks the lifeline at the onset of a fall, similar to a seatbelt, which helps to prevent a worker from hitting the ground or a lower level. Despite the misconception that they might be bulky and heavy, modern designs can be quite compact and lightweight. They are suitable for fall protection as they are designed for this purpose specifically and don't require constant adjustment, as they automatically retract to accommodate movement.
